Jin is a mild-mannered vagrant ronin who carries himself in the conventionally stoic manner of a samurai of the Tokugawa era. Using his waist-strung daishou, he fights in the traditional kenjutsu style of a samurai trained in a prominent, sanctioned dojo.

Jin wears glasses, an available but uncommon accessory in Edo era Japan. Jin seldom talks and Fuu seems to prefer him to Mugen. He is reputed to have killed his dojo master and his history is shrouded in mystery.

Martial arts are an expression of power, showcasing the potential of the human body when pushed to its physical limit. It also makes for exciting anime, and allows animators and directors to showcase their prowess as things get heated.
